V = \pi r^2h\\V=(3.14)(5cm)^2(21cm)\\V=(3.14)(25cm^2)(21cm)\\V=1648.5cm^3

Therefore, the answer to your question is b. 1 648.5 cm³.

Good morning!

Volume of Cylinder = (π) (r)² (h)

where:
π (pi) = 3.14
r = radius,  5 cm
H = height, 21 cm

Substitute the given values to the formula:
Volume = (3.14) (5 cm)² (21 cm)
             =  (3.14) (25 cm²) (21)
             =   1,648.5 cm³ or cubic meters

The answer is b.
